-uv Stop!!??

[bv_reefer]

-Ok I got a 33-gallon that i'm plannin 2 start cyclin' next week and need 2 know what UV STOP means!

-It's been buggin' me for quite a while now because every1 says that double-ended hqi bulbs like mine need a 3mm sheet of glass covering them 2 block out the harmful uv rays that they emit, that can trouble the skin of fish.

-So the main question iz...IF I HAVE ''UV STOP'' LABELED ON MY
DOUBLE-ENDED BULBS DOES THAT MEEN THAT I STILL NEED GLASS? OR DOES THAT BLOCK OUT ALL THE HARMFUL AMOUNTS OF UV RADIATION BY IT'S SELF LIKE SINGLE-ENDED BULBS DO???
